Abstract

PURPOSE:To output quickly a Kanji (Chinese character) whose reading the operator cannot understand, by displaying all radicals having the same number of strokes as the radical of the Kanji to be retrieved and designating a radical of these displayed radicals and displaying all Kanjis having the designated radical. CONSTITUTION:When the operator operates a radical key, the device is set to a radical mode. The operator inputs the number of strokes of the radical of the Kanji to be retrieved with a ten key. Then, an area corresponding to the inputted number of strokes is retrieved by an index 61 of a radical Kanji processing part 6, and a radical group having the inputted number of strokes is listed together with numbers corresponding to individual radicals on the display screen of a display device 8. When the operator inputs a corresponding number on the list with the ten key, all Kanjis having the designated radical are read out from a radical Kanji table 63 and are displayed together with numbers corresponding to individual Kanjis as a list on the display screen. At this time, the operator inputs the number of the objective Kanji with the ten key to display the retrieved Kanji on the screen. Thus, the character input is performed quickly.

Description

[Detailed Description of the Invention] Technical Field This invention relates to a kana-kanji conversion device that converts a kana character string input according to the pronunciation of the characters into kanji or kanji-kana mixed sentences, and in particular, a method for outputting kanji whose reading is unknown. Regarding.

Background Currently, Kana-Kanji conversion devices in general use employ an onkun input method in which the reading of a Kanji is input as a method for specifying any Kanji.

However, this method has the drawback that it is not possible to specify unknown kanji or kanji whose readings are unknown. Therefore, one possible method for specifying kanji whose pronunciation is unknown is to utilize radicals, which are characteristic of the shape of kanji.

There are two ways to use radicals: inputting the pronunciation of the radical or inputting the code of the radical, but in the former case, you do not know how to read the radical itself, and in the latter case, you need to use an index table. There are disadvantages such as having to repeat the process repeatedly, and the transmission is not efficient.

OBJECT OF THE INVENTION Therefore, the object of the present invention is to provide a novel method that can quickly search for a target Kanji using the radical of a Kanji.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention inputs the number of strokes of a target radical of a kanji from an input means, causes a display means to display all radicals with the number of strokes, and displays the displayed part. Specify and input the desired radical of the kanji from the head group, display all kanji that have this specified radical, specify and input the desired kanji from the displayed kanji group, The basic feature is to efficiently output the kanji you want to search for.

Preferably, when displaying a radical or kanji on the display means, the radical or kanji is displayed together with an identification code corresponding to the radical or kanji.
When specifying a kanji, enter this identification code. The identification code is, for example, a number that can be specified using a numeric keypad, which allows for quick input specification and makes the search even more efficient.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Embodiment An embodiment will be described together with a description of a text processing device equipped with a kana-kanji conversion device, which forms the background of the present invention.

In FIG. 1, 1 is a keyboard device, which, as shown in FIG. 2, includes a kana key 11 in which kana characters are arranged in alphabetical order, and a numeric keypad 12 in which numbers are arranged.

Conversion control keys 13 and 2 for converting kana sentences inputted using the kana key into kanji with corresponding readings; and 2, which is a feature of the present invention, allows searching for the desired kanji by specifying the radical of the kanji to be input. It is provided with a radical control key 14 for setting a radical mode, and a cursor control key 15 for moving a cursor mark displayed as an input position on two display screens. By operating any key on the keyboard device l, a corresponding character code or related codes and control codes are generated and given to the CPU 2 via the bus B in FIG. C.P.
U2 executes various editing processes using a control program that is stored in advance in area 31 of ROM 3 and will be explained below. An area 32 of the ROM 3 stores a table for converting the numerical code inputted from the numeric keypad 12 into corresponding binary data or inversely converting it.

4 is a RAM, which is divided into multiple buffer areas,
A sentence buffer 41 stores input text data converted from kana characters into sentences mixed with kanji in the input order, a kana buffer 42 stores the kana characters input from the kana key 11 in the input order, and a line that performs input editing work. The line buffer 43 memorizes the text data and transfers the data to the text buffer 41 when one line of text editing is completed, and temporarily stores the numerical code input in radical mode, which will be described in detail later. An IN buffer 44 for storing, flag areas 45 and 46 for respectively storing flags 1 and 2 (flag: FLAG) used for flow control in radical mode, which will be described later, and other areas for controlling the system of this apparatus. The memory area 47 includes various flags used for the data and an area 47 for a data buffer (buffer may be abbreviated as Buf hereinafter).

5 is a kanji conversion unit that converts the kana characters stored in the kana buffer 42 into kanji-mixed sentences with the same pronunciation, and the kanji-mixed sentences (converted sentences) converted here are sent to the above-mentioned line via bus B. The data is transferred to the buffer 43.

7 is a control unit for controlling the display of the CRT display device 8, including a display memory 71 for storing data to be displayed; and 9 a control unit corresponding to each display section of the screen for displaying a cursor mark at an input position on the display screen. It is provided with a Kahnle buffer 72 which stores data //1 in a storage area formed by the following steps. Note that since the display data stored in the display memory 71 is a character code, a corresponding character shape is displayed by a pattern generator (not shown). Also, C
As shown in FIG. 6, the display screen of the λT display device 8 consists of a large data area 81 at the top and a one-line message area 82 at the bottom.

Reference numeral 9 denotes a printer control section for controlling printing of the dot printer 1o, which receives the data in the text buffer 41 via the bus B and outputs it to the printer 1o for recording.

Reference numeral 6 denotes a radical kanji processing section used in the present invention, which includes an index 612, a radical stroke count table 62, and a radical kanji table 63, and has a concrete configuration as shown in FIG. The index 6D stores the start address data for each radical stroke number in the radical stroke number table 62, and the third
As shown in the figure, a numeric code 61a consisting of two characters and the head address data 61b are sequentially stored in pairs. In the radical stroke number table 62, for each corresponding radical in the radical kanji table 63, a radical code 62a and the start address data 62b of the table 63 are sequentially stored in pairs. In the radical kanji table 63,
The character codes of kanji are stored sequentially for each part of the same heading. Specifically, the order of storing in the index 61° tables 62 and 63 may be the order found in C6226 of the JIS standard.

To explain in more detail, the radical kanji table 63 stores kanji that belong to the radical in order, starting with one stroke of the radical. For example, as shown in Figure 4 (C), the kanji character ``口'', which belongs to ``口'' (kunikamae), which is one of the three strokes in the radical, is set as the first address set, ``4'', ``
Prisoner ",'cause",...

“Country”, I remember it in order. The radical stroke number table 62 sequentially stores radical codes belonging to the number of strokes for each number of strokes of each radical, and as shown in FIG. Let ``口'' (kuchi) be the first address An, and have the corresponding first address Ampe of the radical kanji table 63 as a pair, and hereafter 9
0" code, "Sat □" code, etc. are stored in this order. For example, if the index 61 is three-sided as shown in FIG. 4(a), the numbers //o//, //
3 // code and radical stroke count table 621. The first address An of ``A'' is stored as a pair.

Referring again to FIG. 3, 64 is the index 61 mentioned above.
The address circuit (ADRI) is an address circuit (ADRI) to which address data is input via bus B in FIG. index 61
The address data read from the radical stroke number table 6
2 address circuit 65 (ADR, 2). The address circuit 65 also operates a counter 67 (Kl
) The address is set according to the binary data. The address data read from the radical stroke number table 62 is sent to the address circuit 55 (ADR3) of the radical kanji table 63.
Can be seen. On the other hand, the read radical code is stored in the output buffer 69. The address circuit 66 is also addressed according to the counter 67, and the Kanji code read from the radical Kanji table 63 is stored in the output buffer 69.

Next, the operation will be specifically explained according to FIG. 5 and FIGS. 5A, B, and C.

When a key is pressed manually from the Japanese key 11 to input a text, steps 100 and subsequent steps are executed. The input character code is stored in the corresponding input registers of the kana buffer 42 and the line buffer 43, and furthermore, the data in the line buffer 43 is transferred to the input line (cursor mark display line) of the display memory 71, and the previous The cursor buffer 72 is then incremented by one character, and the cursor data is stored in the next character area (steps 100-104).With this operation, the intervening kana character is is displayed at the input position, and the input mark is displayed at the next position.

By repeating the above operations, the kana sentence to be converted into a sentence mixed with kanji is stored in the kana buffer 42 and displayed. When the operator operates the conversion key 13 here, steps 110 and subsequent steps are executed.

In response to a conversion command, the data in the kana buffer 42 is supplied to the kana-kanji converter 5, and a sentence (converted sentence) with kanji mixed in with the same reading as the kana sentence is read out from the kana-kanji converter 5. The read converted sentence is written to the location where the kana sentence was stored in the kana buffer (steps 111 to 12).
112). Next, the data in the 117th line buffer is stored in the corresponding line area of the display memory 7.1, replacing the previous display data, and the data in the cursor buffer is modified by the difference between the number of characters in the kana sentence and the number of characters in the converted sentence. Display a mark at the next input position. At the same time, the kana buffer is initialized (steps 113 to 115). Through this conversion process, the target text is input and displayed. By repeating the above kana input and conversion, a desired sentence is input and displayed, for example, as shown in FIG. 6(a). In addition,
In FIG. 6, the ○ mark indicates one character, the `` mark indicates a line break mark, and the - mark indicates a cursor mark.

Now, when the operator attempts to input a kanji whose pronunciation is unknown (in this example, "kuni"), the radical mode is set as explained below.

When the operator operates the radical key 14, steps 120 and subsequent steps are executed. First, the device is set to the radical mode, and it is determined whether data is stored in the kana (sofa 42).If you operate this radical key 14 before the kana-kanji conversion has been performed, the data remains in the kana buffer. First convert the data that is present and put it away (steps 121 to
23).

Note that at this time, the kana sentences may be left as they are as text data. In the following step 124, the display memory 7
1 and erase the display screen. Furthermore, I
The data of 00'' expressed by the numerical code is stored in the N buffer 44 (step 125). Next, the guidance character data of ``<number of radical strokes>'' is stored in the display memory 71 corresponding to the guidance area 82 (Fig. 6). is stored, and subsequently the data in the IN buffer 44 is stored (step 12).
6°127). Next, set the data in the cursor buffer so that the cursor mark is displayed at the second digit position of the number “00” displayed by the buffer, and
Settings are made so that data can be written to the second digit position of the N buffer (steps 128 and 129). As a result of this operation, the screen is displayed as shown in FIG. 6(b).

Here, the operator should input the number of strokes (in this example, de, is three sides) of the radical of the kanji to be searched (in this example, it is "mouth" (kunigamae)) (using the numeric keypad 12, use the number keys) Step 130 and subsequent steps are executed by operating the numeric keys.

In step 131, it is determined whether the mode is radical mode. Since the radical mode has been previously set in step 121, the process advances to step 132. If it is not the radical mode, the process shifts to the character input process described above as the normal text input mode. At step 132, the input numeric code is stored in the input position of the IN buffer 44. Since the second digit position is currently being specified, the entered numerical code is stored in the second digit. Then, the input numerical code is stored and displayed at the cursor position indicating the input position in the guidance area of the display memory (step 133).

In the next step 134, it is determined whether the cursor position is at the first digit. If it is the second digit, IN, (the input position of the sofa and the cursor/sofa are updated by one character (step 135). With this operation, input the second digit of the number of strokes, and use the numeric keypad again to enter the number of strokes. Enter one digit. For example, if there are three strokes, enter "03".However, since /100" has been entered in advance, the second digit may be skipped using the cursor key 15.

When the input of the first digit is completed, the process proceeds from step 134 to step 136. The flags are checked, but since both FLAGI and FLAG2 are reset initially, the process proceeds to the flow shown in FIG. 5A.

In step 150 of FIG. 5A, index 61
The area corresponding to the number of input strokes is searched. That is,
A numeric code 61a is accessed to the index 61 according to the address circuit 54 (ADRl) in FIG. 3 and stored in advance.
is compared with the numerical code stored in the IN buffer 44, a matching area is selected, the leading atrus of the corresponding area of the radical stroke number table 62 is sequentially output, and this is sent to the address circuit 65.
(ADR2) (steps 150 and 151).

Subsequent steps 152 to 159 list the group of radicals with the input number of strokes on the display screen along with the numbers corresponding to the individual radicals. In the initial stage, the counter (K1) which is reset is incremented by 1, and the binary number of K1 is RO.
It is converted into a numerical code using the table 32 of M3 (for example, converting "00000001" into character codes such as "0" and '1") and stored in the corresponding position of the data area of the display memory (steps 152 to 154). ).Furthermore, the address circuit 65 (ADR2) is set to the address corresponding to the data of 1, the radical code is read from the radical stroke number table 62, and is stored in the output Buf 59.Continuing,
The data of this output Butt is stored in the display memory 71 at a position following the previously stored numerical code (step 156
~157). Next, +1 is added to K1, and a comparison is made to see if the number of strokes is the end of the input radical, that is, whether it is equal to the address of the next area of the area read from the index, and the above operation is repeated until they match (step 158). ~1
59).

If they match, the guidance data ``radical display'' is stored in the guidance area of the display memory, and the IN buffer is initialized (memorizing the numerical code 700''), and this IN buffer data is stored in the guidance area following the above data. (Steps 160-1)
62). Then, point the cursor buffer to the second digit position of the numerical code of the guidance data, and
1 is reset, ADR2 is set to the same address as in step 151, and FLAGI is set (steps 163 to 166). As a result of this operation, in the data area of the display screen, a list of radical groups that are paired with numbers and equal to the number of input strokes is displayed, as shown in FIG. 6(C).

Here, the operator inputs the corresponding number in the list using the numeric keypad 12 in order to select the desired radical. The kanji you are searching for is “kuni”, so use the radical “ku”.
Enter “02” corresponding to . By inputting this number, the operations from step 130 onwards are executed again, and when all 02'' are input, the process advances from step 134 to step 136.

Since FLAGI is set, the process proceeds to the flow shown in FIG. 5B.

In step 180 of FIG. 5B, IN buffer 44
Convert the numerical code of the radical number input stored in RO1M3 into binary value data using the conversion table 32 of RO1M3,
It is stored in the counter 68 (K'2). Next, set K1 to +1
Then, ADR2 is set to the address corresponding to the binary data of xi, and a determination of 2 is made for K1- (step 18).
1-183).

This operation is repeated until a match is made, and the area of the table 62 corresponding to the radical set in the IN buffer is selected. When the corresponding area is selected, K1 and K2 are reset, and the display memory and IN buffer are initialized (steps 184 to 186). Next step 187
Now add +1 to 1. Next, the address data read from the radical stroke count table 62 is sent to the address circuit 66 (A
DR3) (step 188). That is, address data corresponding to the first address of the radical kanji table 63 belonging to the designated radical is supplied to the ADR3. K
Convert the binary data of 1 into a numeric code using the conversion table 32, store this numeric code in the corresponding input position of the data area of the display memory, and set ADR3 to the address corresponding to 1 (initially , the character code is set to the address of the area where the character code of the first kanji character, that is, in this example, ``口'' is stored), the character code is read from the radical kanji table 63, and is stored in the output Buf.

Furthermore, the character code of this output Buf is stored in the data area of the display memory following the numeric code (steps 189-193). +1 to Kl in next step 194
, and the operations of steps 188 to 194 are repeated until the kanji area of the corresponding radical is completed. As a result of this operation, all the Kanji characters having the designated radical are displayed as a list on the display screen along with numbers corresponding to the Kanji characters.

In the next step 196, the guidance data ``Kanji'' is stored in the guidance area of the display memory, and the numeric code ``00'', which has been initialized and stored in the IN buffer, is stored following the guidance data ( Step 196°197). In step 198, as described above, 1. The cursor buffer is set to the second digit position, and the input position of the IN buffer is set to the second digit position. , then reset K1, set AD-R3 to the address read from table 62, and set FLAG.
While resetting I1. Set F LAG2 (
Steps 199-202).

Through the above operations, guidance is displayed on the screen together with a list of kanji characters, as shown in FIG. 6(d).

At this point, the operator inputs the number of the desired kanji using the numeric keypad 12 in order to obtain the desired kanji. Step 130PJ in FIG. 5 is executed again. FLAG
Since l has been reset and FLAG2 is now set, the flow advances from step 137 to the flow shown in FIG. 5(C).

In step 220 of FIG. 5C, the previously input numerical code to be stored in the IN buffer is converted into a binary value by the table 32 of the ROM 3, and is stored in the counter 6g (K2). After that, the addresses of ADR3 are sequentially set without incrementing Kl by 1, and the process is repeated until x1=x2 (steps 220 to 223). This operation selects the area of the designated number in the radical kanji table 63. In this example, the "Country" area is selected. Subsequently, in step 224, the corresponding character code (country code) is output from the radical kanji table 63 to the output Buf 69.

Then, in step 225, the data of this output Buf is stored in the input position of the row buffer 43. Through the above operations, the desired kanji that was being searched for is obtained and entered as part of a sentence. After that, the counter's Kl
, 2 and FLAGI, 2 are reset, address circuits ADR1, 2, and 3 are initialized, and the display memory is initialized (step 226).
~229). This is to return to the text input mode as shown in the screen in Stella 4Ashi 6 (a) below, and reads out data sequentially from the beginning of the corresponding area of the text buffer 41 and stores it in the display memory, and also inputs data from the line buffer 43. The data is stored in the input row position of the display memory 71. Further, after setting the cursor buffer to the next input position, this radical mode is canceled (steps 230 to 233).

As a result of the above operations, the screen is displayed as shown in FIG. 6(e) and 1. The searched kanji ``country'' will be displayed.

In this way, the operator can easily and quickly input characters by simply inputting the number of strokes of the radical, and then selecting the radical or kanji in the displayed list.

In the above embodiment, in order to select a target radical or kanji from a group of radicals or kanji, numbers are displayed in pairs with the radical or kanji, and by inputting this number, Although one is specified, the selection may be made using the cursor key 15 instead. Simply display radical groups, kanji groups,
Place the cursor mark on the desired radical or kanji and press the execution key to specify it.The cursor position should be associated with the data at that position, and that data can be retrieved.

Further, the technology disclosed herein can be similarly applied to a system equipped with a kanji tablet type input device in which kanji are arranged. As a modification of this system,
Radicals may be arranged on a kanji tablet in ascending or descending order of the number of strokes, and when a radical is designated, all kanji having that radical may be displayed. In this case, since it is sufficient to simply select the displayed kanji, the operation becomes simpler.

Effects As described above, according to this invention, by simply inputting the number of strokes of the radical of a kanji whose reading is unknown, the desired kanji can be searched for by a simple selection operation, and kanji whose reading is unknown can be quickly retrieved. You can do it.
